摘要
在分析泵站现地监控单元的基本功能、技术指标的基础上,讨论了基于AT89C52单片机的泵站现地监控单元硬件结构原理及其实现;阐述了软件设计要点;就行业内现场常用的循环码编码器(码盘),介绍了其译码方法;考虑到支持各种上位监控组态软件,重点讨论了MODBUS通讯协议的实现.最后,介绍了该仪器在泵站计算机监控系统建设中的应用.
According to the fundamental function and technical indicators of the pump station local control unit, and based on processor AT89C52, the unit construction principle and its realization and the coding method of traying of the pump station local control are discussed. The key points of software design was illustrated and the decode method of the Cyclic Code Encode extensively used on site was introduced. And considering the support for Monitor Configuration Software the realization of MODBUS protocol was mainly discussed. Inaddition, the application condition of this instrument to the pump station control system was provided.
